a
Values are means±standard deviations of the log10 most probable number per gram of feces for individual pig samples. Mean values within a column with the same superscript are not significantly different (p>0.05) using Duncan’s Multiple Range Test.
b
Three pigs in SPD treatment died during the experiment (days 10, 12, and 17).
